The PF7 system can operate in-line with or off-line from a digital web press. At AGS, pre-printed rolls are mounted on the Standard Hunkeler UW7 30-wide unwinder, threaded through the double plow folds, and then into the Standard Hunkeler CS6 rotary cutting and LS6 stacking module. Perforations are applied in the web direction for accurate high-speed plow-folding and lay-flat signatures at up to 500 feet per minute. The folded web is cut into four-, six-, or eight-page signatures, which are cleanly stacked as individual book blocks for easier downstream handling.

“The PF7 gives us the substrate flexibility publishers need, and fast changeovers for different multiple-up impositions,” said Kriemelmeyer. “We now run maximum efficiency on short and long runs because this system allows quick changeovers between formats.”

AGS first saw the PF7 system earlier this year at the Hunkeler Innovationdays event in Switzerland, and determined it would be the most streamlined approach for finishing inkjet digital rolls. “We value the trust AGS has placed in us,” said David Reny, executive vice president, Standard Finishing Systems. “They and other CGX-affiliated companies have embraced the Hunkeler and Horizon postpress portfolio, and we remain committed to helping them reach new levels of production efficiency.”
